Original Abstract
Thermal noise and polarisation noise are the main sources of voltage or current fluctuation in piezoceramic samples. Noise spectral density is proportional to sample equivalent series resistance and decreases with increasing frequency. Induced electric charge fluctuates and character of this fluctuations is 1/f due to the fact that dielectric conductivity is proportional to imaginary part of permitittivity and frequency. We proved, in accordance with experimental results, that at low frequencies is the polarisation noise of 1/f type.
